The Petrarch Exegesis in Renaissance Italy Database (PERI) is a free, fully searchable catalogue of print and manuscript copies of commentaries, of lectures, and of other modes of exegesis and forms of assistance for readers found in editions (lives, annotations, short notes, indexes, and related material) and other sources such as glossaries, dialogues, and letters. The database covers material produced in Italy between 1350 and 1650 and is focused upon exegesis of Petrarch’s vernacular works, both the Rerum vulgarium fragmenta and the Triumphi. The census forms part of the collaborative project Petrarch Commentary and Exegesis in Renaissance Italy, c. 1350-c.1650, funded by the Arts and Humanities Research Council (January 2017-December 2019).
